USE
Deoxys-Speed @ Life Orb
Ability: Pressure
EVs: 236 Spd / 252 SAtk / 20 Atk
Naive/Hasty Nature
- Psycho Boost
- Ice Beam
- Superpower
- Knock Off/HP [Fire]/Fire Punch
Role: Late-Game Cleaner
What it does: With nearly perfect coverage and speed that's over kill, it can outspeed many things such as ScarfChomp, and +1 Base 100's such as Charizard X. Psycho Boost, even though first on the list, is the strongest but should be reserved only for things you are not sure you can kill with other moves (The -2 drop hurts). Ice Beam is your coverage, although hitting just about everything weaker, it helps kill Landorus(T), Garchomp, or about anything that is 4x weak to it. Superpower OHKO's Mega TTar (With 4 HP EVs) with Stealth Rock down, and also takes a chunk of health away from walls such as Blissey. The last slot is your choice - Knock Off is usually the best option for really just smacking items off.There is also HP [Fire] which helps hit Aegislash and Ferrothorn, but if you want to hit on both sides reliably you can choose Fire Punch (There's only a 0.7% difference).
Good Teammates: Anything that can do major damage helps Deoxys-S greatly. Even with SAtk investments, Deoxys-S does not hit very hard due to only getting a 1.3x boost with Life Orb. Usually any Pokemon that can bring a Pokemon's Health below 50% helps it immensely. Entry hazards also help a lot to break Sashes, Sturdy, or maybe even pressure a switch, and make Deoxys' cleaning even easier. Pokemon that can also help clear out status make Deoxys put a big smile on it's face, even without a mouth, as almost every status cripples him.
What counters it: Anything faster then it. Deoxys is outsped by 105 Scarfed mons, meaning Landorus, Keldeo, Lati twins, and many others work very effectively to counter Deoxys. Pokemon that can survive a hit on switch or have a decent amount of health left can usually live a hit and smash it with a powerful move. As said above, if you can, just about any status cripples Deoxys and he wants to avoid it. Lastly, anything with Sucker Punch or a powerful priority basically makes it's life A LOT harder.
Any additional info: Deoxys can work as an effective lead - this is due to many people bringing in their anti-lead counter (say, Espeon) until they realize that it's gone due to it having a surprise factor. You might want to use it while you can, too, as everyone is beginning to realize that Deoxys-S is now usually an attacker. I also cannot stress this enough -
Always bring it in when everything is weakened. Trust me on this one, it's incredible speed allows it to be one of the only late-game cleaners that can switch up moves.
Do not use
Tyrantrum @ Life Orb
Ability:
Rock Head Strong Jaw
EVs: 252 Spd / 252 Atk / 4 HP
Adamant/Jolly Nature
- Dragon Dance
- Stone Edge
- Dragon Claw
- Earthquake/Elemental Fangs
Role: Physical Sweeper
What it does: Tyrantrum is one of the two Pokemon with Rock Head and Head Smash making it hit ridiculously hard. The goal is simple, the same as almost any Dragon Dance Sweeper. Try to get as many as Dragon Dances up as you can, and begin the rampage! Head Smash paired with Rock Head is arguably the best move in the game, with stab it hits an insane 225 Base Power. Sadly, Tyrantrum doesn't seem to get Rock Head as of now so it has to go with Stone Edge. It's best Dragon coverage move is Dragon Claw. Earthquake is the final move to hit steel types mainly. You can choose any other elemental fang if you wish, though, but Earthquake is generally the best option.
Good Teammates: Anything that lets Tyrantrum set up easily helps. Due to having rather bad typing being weak to many forms of priority/moves, and having a below decent amount of SDef, Tyrantrum definitely likes going with things helping it setup. Other good teammates are tanks that can help it sponge special attacks, or just attacks in general. Tyrantrum also likes the sandstorm as it increases it's special defence greatly.
What Counters it: Any super-effective special attack will destroy Tyrantrum's hopes and dreams. Like many other sweepers, it does not enjoy Thunder Wave (Thundurus), and Will-O-Wisp. Being weak to 6 types that are quite common this generation, it's hard for Tyrantrum to ever get a safe Dragon Dance up. The best counter is just what I said above, any super-effective move on the special side makes it fall on it's knees.
Any additional Info: I haven't had much time to test it out myself, but the reason it isn't very good is due to it's mediocre speed and horrible Special Defence, it's pretty much outclassed by other DDance sweepers as it's only real edge over them is having a super powered Head Smash with no recoil. But, on the other side it also can use Sandstorm very well, usually getting at least one DDance up. As of now, it isn't good due to Rock Head not being released, but once it is it might be pretty viable.
Edit:
This is the "Pokeaim Tank Zard set" if this isn't what you used, if it isn't then there's also the other one from the Charizard discussion on the OU page here. Here are both sets:

If you want I can explain both sets, just put a message here and I'll be glad to help.
Edit 2: Edited Rock Head Tyrantrum as I forgot it wasn't realeased (Thanks Sergeant Sppoky) and gave one more example of what Deoxys-S could outspeed with the EV Spread. (Thank you DC-Shadow)
